Garden State Treatment Center provides outpatient addiction and co-occurring mental-health care at 350 Sparta Avenue, Suite A201, in Sparta, New Jersey. Current official pages describe partial hospitalization/partial care (PHP), intensive outpatient (IOP), evening IOP and standard outpatient treatment.
PHP commonly meets five or six days a week for about six hours a day. IOP generally meets three to five days weekly for three to four hours per session and exceeds nine clinical hours per week; standard outpatient care is typically one or two sessions weekly. Overall treatment length is individualized. The provider advertises short-term accommodation for some partial-care clients, but presents the clinical program as outpatient rather than 24-hour residential treatment.
Garden State does not provide detoxification in-house. Its current partial-care page says clients who need detox are directed to an appropriate facility before outpatient treatment. The center treats substance-use disorders and co-occurring mental-health concerns, accepts most major private, employer-sponsored and TRICARE plans subject to verification, and offers individualized aftercare and an alumni program.
